CAR-S EAT.

SPECIFICATION forming part of Letters Patent No. 657,480, dated. September 4, 1906.

Application filed April 25,1900,

To all whom it may concern.-

Be it known that I, THOMAS B. CANN, of Wakefield, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Car- Seats, of which the following is a specification.

This invention relates'to a car-seat having a reversible 0r swinging back, a foot-rest frame which is reversible with the back, and a seat which is also reversible, in that its transverse inclination can be varied to raise that edge which is at the front and depress the edge which is at the rear.

The invention has for its object to provide simple and efficient means whereby the reversal of the back causes also a reversal of the position of the foot-rest frame and seat. 7

The invention consists in the improvements which I-will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a top plan view of a car-seat embodying my invention, the seat-cushion being removed. Fig. 2 represents a section on line 2 2 of Fig. 1.

The same reference characters indicate the same parts in both of the figures.

The rigid supporting frame of the seat comprises the two end pieces 2 2 and the connecting-bars 3 3, the upper sides of the connecting-bars being inclined to form guides for the seat-supporting slides 4 4:, the latter having inclines 5 5 on the under sides of their end portions, bearing on the inclined upper surfaces of the bars 3.

6 6 represent rock-shafts which are jour-. naled in bearings on the end pieces 2 2 of the seat-frame. To said rock-shafts are affixed arms 7 7 and cams 8 8. The arms 7 7 are provided on their outer ends with studs 9 9, which enter slots 10, formed in the crossbars 11 of the foot-rest frame, said frame comprising the arms 11, which are pivoted at 12 to the seat-frame, andthe parallel footrests 13 13, which are attached to and extend between the arms or cross bars 11. The cams 8 Shear against lugs 14 14., formed on the seat-supporting slides 4t. The arms 7 and cams 8 of one rock-shaftproject at a difierent angle from the arms 7 and cams 8 of the other Serial No. 14,238. (No model.)

I rock-shaft, as shown in Fig. 2, the relative arrangement being such that when the arm and cam of one rock-shaft are raised the arm and cam of the 'other rock-shaft are depressed, thus causing the arms 7 7 to act conjointly in holding the cross-bars 11 of the foot-rest frame in an inclined position and the cams 8 8 to act conjointly in holding the seat-supporting slides 4 at one end of their movement.

16 represents the seat-back, to the ends of which are affixed metal arms 17, the lower ends of which are provided with ears 18 18. To said ears are jointed two parallel'links 19 19, the lower ends of which are' fixed rigidly to the rock-shafts 6 6.

The operation is as follows: When the seatback is moved from one edge of the seat to the other, the swinging movement of the links 19 causes a partial rotation of the rockshafts 6 6, thus elevating the arms and cams of one rock-shaftand depressing the arms and cams of the other rock-shaft, the result being a reversal of the positions of the footrest frame and of the seat-supporting slides, the forward edge of the seat-frame being raised and its rear edge depressed, While the foot-rest under the forward edge of the seat is raised out of the way and the foot-rest under the rear edge of the seat is depressed to an operative position.

My invention is not limited to the exact details of construction and arrangement of parts here shown, and the construction and arrangement may be variously modified without departing from the spirit of the invention.

In Fig. 1 I have omitted one of the arms 7 7 from each shaft.

I claim In 1. In a car-seat, a fixed seat-frame, a footrest frame pivoted to the seat-frame below the seat and comprising cross-bars having slots, and foot-rests which are alternately elevated and depressed by movements of the frame, two rock-shafts journaled in hearings in the seat-frame and each having two arms engaged with the slots in the cross-bars of the footrest frame, a reversible seat-back, and parallel links jointed to the back and attached rigidly to the rock-shafts, the arms of one of one shaft are depressed, while the arms rock-shaft being so arranged relatively to the arms of' the other rock-shafit'that when: the back is reversed the arms of one rock-shaft are depressed, while those of the other rock-. shaft are raised, whereby a reversal of the position of the back causes a reversal of the position of the foot-rest frame, as set forth. l

2. In a car-seat, a fixed: seat-frame having, seat-guiding inclines, a foot-rest frame 'pivoted to the seat-frame below the seat. and comprising cross-bars having slots, and footrests which are alternately elevated and depressed by movements of the frame, two rockshafts' journaled i-n bearings in the seat-frame and each having two arms engaged with the t slots in the cross-bars of the seat-frame, and two seat-inclining cams, a reversible seatback, parallel links jointed to the back and rigidly attached to the rock-shafts, andseatsupporting slides engaged with the said cams and having inclines guided by the inclines. on the seat-frame, the arms and cams of one rock-shaft being so arranged: relatively to the arms and earns of the other rock-shaft that when the back is reversed the arms and cams and cams of the other shaft are raised, whereby areversalof the position of the back causes a reversal of the position of the foot-rest frame and of the seat, as set forth. 7

3. In a car-seat, a fixed seat-frame having seat-guiding inclines, a reversible foot-rest framebelow the seat and comprising parallel foot-rests and cross-bars connecting the ends of the rests, two rock-shafts journaled in the seat-frame andhaving rigidly-attached cam s, seat-supporting slides having inclines guided by the inclines on the seat-frame and having lugs bearing on said cams, a reversible back,

"parallel links jointed'to the back and rigidly attached to the rock-shafts, and connections between the rock-shafts and the foot-rest trams, whereby areversal of the position of theback causes also a reversal of the position of the. foot-rest frame, the cams on one rock-4 shaft being so arranged relatively to the cams on the other rock-shaft that a reversal of the position of the back causes also a reversal of the'posi'tion of the seat.

4, inaear-seaaa fixed seat-frame, two rockrshafts journaled in the seat-frame andhaving rigidly-attached cams, seat supporting slides] halving inclines guided by corresponding inclines on the seat-frame and having lugs hearing on said cams, a reversible back, and parallel links jointed to the back and rigidly attached to the rock-shafts, the cams on one rock-shat t being so arranged relatively to the cams on the other rock-shaft that a reversal of the position of the back raises the cams on one rock-shaft and depresses the cams, on the other rock-shaft, thereby'revers ing the position of the seat.

In testimony whereof I have aflixed my signature in presence of two witnesses.
